Abstract:

Czechoslovakia undertook comparison tests in preparation for the 1965 Vienna session of the CCIR Study Group, which was to adopt a uniform system of color television for Europe. An outline is presented of the Czechoslovak method for the subjective assessment of picture quality the method is derived from the recommended foreign methods, and the results are comparable. A group of 39 observers viewed 10 test pictures and used a system of plus or minus 3 grades for classification. The quality of the color picture in the SECAM system, with closed-circuit TV, was graded better than the NTSC by an average of 0.12. The compatible black-and-white picture in the SECAM system was graded 1.14 points lower than in the NTSC system.
